This came in for a juicy amount of parts to be fitted alongside tuning!
This already had:
Intercooler
Downpipe
Catback
Paddle clutch
We then fitted a Venom550 Hybrid Turbo, ECOTUNE LPFP, VIS HPFP, 4 bar MAP sensor, Ramair Jetstream intake, PCV valve, DI injectors, SIMOS18 ECU.
Alfie wanted us to test and clean the injectors as previous tuner reported that cylinder 2’s injector was causing problems. upon testing the injectors, this became apparent as number 2 injector was all over the place and had failed, So we fitted 4 fresh injectors in 💪🏻
Whilst intake manifold off, we noticed the valves were clearly caked so asked Alfie if he wanted them cleaning (obviously he said yes), making them look nice and brand new!
With this being an early S3, it came from factory with a SIMOS12 ECU which if anyone knows are a terrible ECU when it comes to wanting extra goodies, SIMOS12 doesn’t allow for anything like map switching and so on.
So we got a SIMOS18 plug and play ECU from Kallam which allowed us to then work on tuning the car with map switching, launch control (with it being manual), No Lift Shift and so on.
With a little bit of coding via VCDS we had everything running as should be and car was ready to go on the dyno 👌🏻
Once on the dyno, we started with a base file at 1.6bar to make sure everything was running how it should be and all actual values are meeting specified. Everything was all good apart from there were problems with it not hitting specified boost and we could hear boost escaping with fluctuations on and off. We knew what this was straight away as we have had the exact problems in the past with a certain part fitted. a blow off valve. So that came straight off lol so now working with stock diverter which we find is always best and there is no need for any upgraded DV/BOV at all to help maintain boost at these levels.
Once this was removed, we ran it up again and had no problems with actual hitting specified at all…
We finished at a nice 2bar making some strong and healthy figures for the setup with peak torque at 4800rpm and peak power at 7000rpm!
This was an animal on the road pulling hard through the rev range 🚀
